Abstract

This work outlines a strategy for integrating solar photovoltaic (SPV) and wind energy system (WES) connections. Both rely on storage batteries for energy delivery, which are one of the distribution system’s key advantages. This technique is used to control the voltage at the point of common coupling (PCC) while the SPV system is not producing any power. Using the SPV and batteries as storage energy, the overall system was able to achieve bidirectional grid voltage regulation. During voltage disruptions like sag, swell, and interruption, the bidirectional inverter functions as a normal active power filter, regulating the grid voltage. When the SPV system is using a battery charger, particularly at night time to charge the batteries, it will behave like a conventional switch, and energy will be stored. The proposed technique established the idea of indirect feeder link pathways to regulate voltage regulation, in which as the voltage level rises, a large amount of reverse power flow from WES is automatically regulated by employing the SPV system inverter to charge and store the power. Simulink blocks in MATLAB can be used to model the suggested system. The proposed ...
